Qe = Jc*((2*[BoltZ]*Tc)/[Charge-e])
This formula uses 2 Constants, 3 Variables
Constants Used
[Charge-e] - Charge of electron Value Taken As 1.60217662E-19 Coulomb
[BoltZ] - Boltzmann constant Value Taken As 1.38064852E-23 Joule/Kelvin
Variables Used
Electron Net Energy - (Measured in Watt per Square Meter) - Electron Net Energy is the total energy possessed by Electron.
Cathode Current Density - (Measured in Ampere per Square Meter) - Cathode Current Density is a measure of the flow of electric charge through a given area of a conductor from Cathode.
Cathode Temperature - (Measured in Kelvin) - Cathode Temperature is a physical quantity that describes the level of thermal energy in a system, or the degree of hotness or coldness of Cathode.
STEP 1: Convert Input(s) to Base Unit
Cathode Current Density: 0.47 Ampere per Square Centimeter --> 4700 Ampere per Square Meter (Check conversion here)
